Aluminum - Polymer Capacitors

The SPA151M02B are special aluminum-polymer capacitors by EVOX RIFA, designed for use in AC or DC circuits, in applications ranging from EMI filters, switch mode power supplies, lighting, renewable energy and many other applications. The SPA151M02B capacitors are high-performance with low ESR (equivalent series resistance), high volumetric efficiency and long life-span.

Benefits

The SPA151M02B capacitors offer superior technical performance in a range of applications. Some of the benefits of the SPA151M02B aluminum-polymer capacitors include:

• Low ESR - equivalent series resistance.
• High volumetric efficiency.
• High stability over temperature.
• High temperature range, from -55°C to +125°C.
• Exceptional discharge capability under fault conditions.
• Long service life.

Construction

The SPA151M02B aluminum-polymer capacitors are constructed on an aluminum casing, with two pieces of metallized foil bonded together. Between the two foils is a special polymer which acts as the dielectric. The two pieces of metallized foil are kept apart, due to the build-up of electrostatic charge. This combination gives capacitors superior performance when compared to other available options.

Application Field and Working Principle

The SPA151M02B aluminum-polymer capacitors are suitable for AC or DC circuits and are suitable for use in EMI filters, switch mode power supplies, lighting, renewable energy, and many other applications. The working principle of the SPA151M02B is based on the electrostatic charge, which builds up between the two pieces of metallized foil. As the charge builds up, an electric field is created between the two pieces of metallized foil, resulting in an increase in capacitance. As the applied voltage increases, the charge between the two pieces of metallized foil also increases, resulting in an increase in capacitance.

Advantages of Aluminum-Polymer Capacitors

The unique construction of aluminum-polymer capacitors offers several advantages over traditional capacitors. Some of these advantages include:

• High capacitance density.
• Low ESR (equivalent series resistance).
• High volumetric efficiency.
• High stability over both temperature and voltage.
• High temperature range.
• Exceptional discharge capability.
• Long life-span.

Conclusion

The SPA151M02B aluminum-polymer capacitors are highly versatile and offer excellent performance in a wide range of applications. The combination of high capacitance density, low ESR, high volumetric efficiency, high temperature range and exceptional discharge capability makes them ideal for use in AC or DC circuits. The SPA151M02B capacitors can be used with confidence in applications ranging from EMI filters, switch mode power supplies, lighting, renewable energy and many other applications.
